Terms and Conditions
These terms cover the one thing this site sells: a tagwerk Pro licence. Everything else here is free to read and free to use.
Version of 31 August 2026.
1. Scope and provider
These terms apply to contracts for the purchase of a Pro licence for the app tagwerk, concluded through this website and the checkout linked from it.
The provider and contracting party is Thomas Riedl, caliora, Heubergstr. 54, 83026 Rosenheim, Germany. The full mandatory details, including contact data and VAT identification number, are in the legal notice.
Terms of the customer that differ from these do not become part of the contract, even where we do not expressly object to them.
2. What is being bought
tagwerk is an app for daily notes. The basic version is free. The purchase unlocks the Pro features described on the product page; that description as it stands at the time of purchase defines what is owed.
The licence is a small, signed text file. It is checked on the device, with no account and no connection to a server. One purchase covers every platform tagwerk is released on; the Linux version is free anyway.
A server service is not part of this contract. tagwerk keeps notes as files on the customer's own device; anyone syncing them between devices uses their own storage or their own provider. We neither run nor supply anything for that.
3. How the contract is concluded
What is shown on the product page is not an offer but an invitation to order. The customer makes the offer by triggering the payment at the checkout. The contract comes into being when we accept it — by sending the licence by e-mail, at the latest with the confirmation of the purchase.
The contract language is German or English, whichever the checkout was conducted in. The text of these terms is not stored separately; this page can be read, printed and saved at any time.
4. Price and payment
The price shown at the checkout applies. It includes statutory VAT; there are no shipping costs, because nothing is shipped.
Payment is handled by Stripe. Which payment methods are available is shown at the checkout; they depend on the customer's country and device. Payment is due when the contract is concluded.
Card details never reach us. What a purchase does leave with us is set out in the privacy policy.
5. Delivery of the licence
The licence is sent to the e-mail address given at the checkout as soon as the payment arrives, usually within a few minutes. The mail explains how to activate it.
It is the customer's responsibility to give a working address. If the mail does not arrive, the licence can be sent to the same address again at any time using the form on the licence page. We keep a copy so that this needs no correspondence.
6. Right of withdrawal
Consumers have a fourteen-day right of withdrawal. The details and the model withdrawal form are in the withdrawal notice.
Because the licence is delivered at once, the right of withdrawal ends upon delivery — but only where the customer expressly agreed to that and acknowledged losing it (§ 356 (5) BGB). That is what the tick box at the checkout is for, and why the licence mail repeats the acknowledgement.
Anyone who would rather not have it at once does not buy — and can try tagwerk in its free basic version for as long as they like first.
7. What the customer may do with the licence
The customer receives a simple, perpetual right to use the Pro features for their own purposes — on every device they use themselves, and on every platform.
The licence file is personal: it carries the name given when ordering, and the app displays it. It is not meant to be passed on, published or sold.
We say plainly that we do not prevent this technically. A licence that can be checked without a server can by its nature be copied; that is the price of tagwerk working with no account and no network, and we think it is the right one. What stands here is therefore a request with legal effect, not a claim about technology.
8. Updates
We provide the updates needed to keep tagwerk in conformity with the contract — bug fixes and security updates — for the period a customer may expect after a one-off purchase (§ 327f BGB). Available updates are announced by whichever platform tagwerk was installed from.
This creates no claim to new features. New Pro features are covered by the licence at no extra cost when they appear — but nothing here promises that they will.
9. Defects
The statutory rules on the conformity of digital products apply (§§ 327 ff. BGB). Anyone noticing a defect can write to us at the address in the legal notice, naming the platform and the version — the app shows both under Settings → About.
10. Liability
We are liable without limit for intent and gross negligence, for damage arising from injury to life, body or health, and under the German Product Liability Act.
For simple negligence we are liable only for breach of an obligation whose fulfilment is essential to the purpose of the contract, and only up to the foreseeable damage typical for such a contract.
One note that is meant more sincerely than a liability clause: tagwerk keeps notes as ordinary text files in the customer's own folder. Backing them up is the customer's responsibility — and because they are ordinary files, they can do it by whatever means they like.
11. Consumer dispute resolution
We are not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board. That does not mean we will not talk: an e-mail gets an answer.
12. Applicable law
German law applies. For consumers, the mandatory consumer protection rules of the country of their habitual residence remain unaffected.
Should any provision of these terms be invalid, the remainder stay in force.
